Title: Data communication system with reduced risk of transmission errors
Inventor: SETO KENICHI
IPC: G06F13/38
Filed: 1994-06-30
Abstract: A data communication system comprises a main device 1 with a first microcomputer and an operating device 2 with a second microcomputer. The devices are connected to each other by a first wire 3A and by a second wire 3B. In addition to that, input interrupt terminals INT of both devices are connected to the second wire 3B. One device starts the sending of data (a) by pulling the second wire to a first level, the detection of this by the other device is signalled back via the first wire and both devices then start (b) an internal timer. When a predetermined time, corresponding to a data item to be sent, has lapsed (d) the sending device pulls the second line again to the first level. This is detected by the other device, which measures the lapsed time and which uses this time to determine the data item sent by consulting preset conversion rules, that give a relation between time and a data element. <IMAGE>

Title: Path protection switching device
Inventor: YAMAMOTO KANTA
IPC: H04L12/437
Filed: 1994-11-16
Abstract: A path protection switching device for an Add Drop multiplexer receives current and reserve signals from the two paths forming a ring network, eg. SONET. In order to reduce the circuitry such as path switch, alarm detecting sections and the like, the selection between the current or reserve channel signals takes place whilst the signals remain multiplexed. The path switch 12 selects one of the channel signals input to it at one time, from the TDM signals output from the first and second Time Slot Assigners (TSAs) 8 and 9. Phase adjusting sections 3 and 4 ensure that the two signals are in phase, which is crucial to enable selection to take place whilst the signals remain multiplexed. VT size detecting sections 5 and 6 enable the device to operate on TDM signals in which channel signals of different sizes are multiplexed. <IMAGE>

Title: Pressure reducing valve
Inventor: KAY FRANCIS XAVIER
IPC: G05D16/10
Filed: 1996-02-12
Abstract: In a valve for use in apparatus providing a relatively low regulated output gas pressure from a high pressure cylinder or the like, the valve is designed to provide a relatively large-diameter valve seating surface (20,) with a relatively small effective valve member cross-section, by forming the valve member (3), as part of a piston and cylinder combination defining therein a chamber (41) exposed to the low-pressure side of the valve. The valve seat or cooperating valve seating (20) may be made of an elastomeric material, with the cooperating valve seating or valve seat being in the form of a prominent ridge so that with increasing pressure differential on the valve, said ridge is driven progressively into the elastomeric material whereby the area of contact is progressively increased.

Title: Method and system for skin effect correction in a multiple transmit frequency induction logging system
Inventor: MITCHELL WILLIAM K
IPC: G01V3/28
Filed: 1997-03-12
Abstract: An induction logging tool is disclosed for utilization in conjunction with surface electronic equipment for measuring a characteristic of subsurface formations. A transmit signal which is comprised of a repetitive sequential series of at least three transmit frequencies is generated by coupling an oscillator 30 to a transmitter coil 38 and a plurality of selectable tuning capacitors 32,34,36. A signal characteristic of the response of the formation to this transmit signal is detected at a receiver coil array 52,54 and two phase sensitive detectors 72,74 are then utilized to generate output signals indicative of the magnitude of the quadrature (X) and in phase (R) components of the formation signal. The output signal of each phase sensitive detector is then utilized to accurately determine the X and R component of the receiver coil signal for each frequency by nulling the output of the phase sensitive detector utilizing a closed loop conversion circuit which eliminates errors due to phase and gain variations. The X and R signals from two or more frequencies are then utilized to correct for skin effect in both magnitude and spatial response.

Title: Optical fire detection system responsive to flicker frequencies
Inventor: SCHULER FREDERICK J
IPC: G08B17/12
Filed: 1998-01-05
Abstract: A method and apparatus for detecting a fire in the presence of radiation from one or more false fire sources. Two radiation detectors (100A, 100B) receive optical signals at first and second radiated wavelengths and produce first and second electrical signals in response thereto. The two electrical signals are correlated (130) in order to generate a correlation parameter and the magnitude of the variation with time of the two electrical signals is exacted at one or more flicker frequency bandwidth by identical flicker filters (110A, 110B). The amplitudes of the two signals at given flicker frequencies are ratioed (120) and this ratio is compared (140) one frequency bandwidth at a time to a threshold ratio value. A fire indication signal is only generated if the ratio and correlation indicators are both positive.
